An object in motion stays in motion while an object at rest stays at rest.
Because it records speed of the car at a certain time, the independent variable should be time and dependent would be speed or velocity. Since it's taken every second, it would be considered instantaneous velocity, which is D.
Answer:
You drive 0.025 miles blind (or 132 ft)
Explanation:
(distance) = (speed) x (time)
(distance blind) = (speed) x (time looking for CD)
(distance blind) = (45 mi/hr) x (2 s) x (1/3600 hr/s) = 0.025 miles = 132 ft
When storm clouds produce lightening and thunder, then, potential energy changes into kinectic energy.
The clouds become negatively charged,and the ground is positively charged during a storm. So there creates a potential difference between the charged clouds and the ground. And when this becomes huge so much that it over comes the electrical insulation cover of air, the electrons jump to the ground.i.e. the potential energy changes into kinetic energy.
Answer:
- 0.75 m
Explanation:
Using the graph as a reference point, the question is ;
What is the displacement of the elephant between 8s and 24s?
The displacement will be the sum of the slope of the graph within the given time.
From time 8s to 16s, the slope m will be;
Slope = (15 - 6) / (16 - 8)
Slope = 9 / 8
From time 16s to 24s
Slope = (15 - 0) / ( 16 - 24)
Slope = -15 / 8
Displacement = 9/8 - 15/8
Displacement = -6/8
Displacement = - 0.75 m
